This initially broadstruck Malaysian 2017 20-sen coin features a rim-restricted second strike on the right side. Die-struck elements were smeared or scraped off both faces of the raised perimeter when the coin moved across the two die faces.

editions of the Jan. 29 issue ofCoin World.

A new name: ‘Skidding coin error’

In his latest “Collectors’ Clearinghouse” column Mike Diamond
identifies a new error coin type — what he is terming a “skidding coin
error.” He explains, this “off-center, rim-restricted second strike
occurs when minimum die clearance abruptly increases so that the dies
only manage to contact the design rim generated during the first strike.”

The coin being described is a Malaysian 2017 20-sen coin, though he
has examined similar errors on U.S. coins. To learn how this
particular error was created, read his column in the Jan. 29 Coin
World, exclusive to the print and digital editions.

Well-informed collectors avoid pitfalls

Online auction portals offer collectors many opportunities to
acquire coins at good prices, but for the ill-informed, they also
offer pitfalls, writes Michael Bugeja in his “Home Hobbyist” column.
Collectors who read books and hobby periodicals and follow the advice
of experts are less likely to fall victim to the unscrupulous, he adds.

The advice of experts “is needed now more than ever, not because the
hobby is dwindling or budgets are exhausted in a week, but because the
thousands of people bidding in these auction portals are not informed
about their purchases and often have no venue to return the items,
fake or not.”

Beware what mold can do to your collection

Proper storage is essential to the preservation of your collection,
writes conservator Susan L. Maltby in her “Protecting Collectibles”
column. However, paper money faces a threat that you may not have
thought about.

“Mold is a problem collectors of paper money encounter,” she writes,
adding, “Mold not only represents a health hazard to the collector, it
can also cause damage to paper-based collections.” Follow her advice
to protect your collection of paper money and related collectibles.
